For example, the connecting member 142 may be hinge-coupled with the external handle 141 and may be adjustable to be connected (coupled, caught) to any one of a plurality of locking protrusions. Since the connecting member 142 is provided so as to be adjustable so as to be connected to any one of the plurality of locking protrusions, it is possible to control the minute amount that is injected into or out of the hollow portion. However, it is not limited to this, and the connecting member 142 may be fixedly connected to a push bar provided in a shape without a stopping protrusion.

1A and 1B, the syringe 100 may include an elastic member 150. The elastic member 150 may be provided between the external handle portion 141 and the outer cylinder 110. For example, the elastic member 150 may include a spring member. The outer handle portion 141 of this syringe 100 is maintained with its rear ends spread apart by the elastic member 150, and when the user applies force to the outer handle portion 141, the spread rear ends are brought together and connected. The member 142 can move the pusher 130 forward or backward. That is, the pusher moving device 140 can slide the pusher 130 forward or backward.

Hereinafter, an embodiment of the present syringe 100 according to an embodiment of the present application will be described.

Referring to FIGS. 1A and 1B, the syringe 100 may be of a backward type in which the pusher 130 slides backward when the user applies force to the external handle 141. This syringe 100 may include a syringe for puncturing blood vessels, a syringe for blood collection, etc.

Referring to FIGS. 1A and 1B, the guide portion 131 of the present syringe 100 may be provided at the rear of the pusher 130. For example, the guide portion 131 of the present syringe 100 may be provided posterior to the point where the external handle portion 141 and the connecting member 142 are connected. Accordingly, the connecting member 142 may be tilted backward from the external handle portion 141 and connected to any one of the plurality of locking jaws.

For example, referring to FIG. 1A, the connecting member 142 of the present syringe 100 is connected to any one of a plurality of locking protrusions of the external handle portion 141 and the guide portion 131 provided at the rear of the pusher 130. It is provided in a state connected to one locking protrusion, and when the user applies force to the external handle portion 141, referring to FIG. 1B, the connecting member 142 is further tilted rearward and the connecting member 142 and The connected push bar 130 may slide backward. According to this manipulation, the pusher 130 of the syringe 100 is moved backward so that the subject's blood or drug can flow into the hollow portion 111 through the injection needle 121.

Figures 2a and 2b are conceptual diagrams to explain an embodiment in which a syringe equipped with a push moving device according to an embodiment of the present application is provided in a forward direction.

Referring to FIGS. 2A and 2B, the syringe 100 may be of a forward type in which the pusher 130 slides forward when the user applies force to the external handle 141. This syringe 100 may include a syringe for drug administration.

Referring to FIGS. 2A and 2B, the guide portion 131 of the present syringe 100 may be provided in front of the pusher 130. For example, the guide part 131 of the present syringe 100 may be provided ahead of the point where the external handle part 141 and the connecting member 142 are connected. Accordingly, the connecting member 142 may be tilted forward from the external handle portion 141 and connected to any one of the plurality of locking jaws. At this time, the locking protrusion of the guide portion 131 has an inclined portion formed to be inclined to be recessed into the inside of the pushing pole as it goes from the rear to the front, and a protrusion extending in the vertical direction to the outside of the pushing pole 130 from the front end of the inclined portion. It can be included.

For example, referring to FIG. 2A, the connecting member 142 of the present syringe 100 is connected to any one of a plurality of locking protrusions of the external handle portion 141 and the guide portion 131 provided in front of the pusher 130. It is provided in a state connected to one locking protrusion, and when the user applies force to the external handle portion 141, referring to FIG. 2b, the connecting member 142 is further tilted forward and the connecting member 142 and The connected push bar 130 may slide forward. According to this operation, the pusher 130 of the syringe 100 is moved forward so that the drug filled in the hollow portion 111 can be injected into the subject's body through the needle 121.

In this syringe 100, when the user holds the outer handle 142 with his hand, the pusher 130 moves forward or backward, so the user can use the outer cylinder 110 and the pusher 130 in the process of puncturing a blood vessel or injecting a drug. It is possible to provide a convenient operation method because there is no need to move the pusher 130 forward or backward by holding it together.

In addition, since the present syringe 100 can be used for all syringes for puncturing blood vessels, syringes for blood collection, and syringes for drug administration, it can replace a significant portion of conventional general syringes and syringes for puncturing blood vessels.
